IDDSI is the International Dysphagia Diet Standardisation Initiative.
Why is this food texture needed?
It can be recommended for people who may have difficulties biting off pieces of food, chewing and swallowing but have some basic or beginner chewing ability. Some people may be able to bite off a large piece of food but may not be able to chew it down into little pieces that are safe to swallow. You only need a small amount of chewing to break down this texture for safe swallowing. It is important that Minced & Moist foods are not too sticky because this can cause the food to stick to the cheeks, teeth, roof of the mouth or in the throat.
What is minced & moist food?
- It is soft and moist but with no liquid leaking or dripping from the food.
- Food has been mashed or minced before serving.
- Biting is not required.
- It has lumps 4mm in size which is about the gap between the prongs of a fork.
- Lumps can be mashed with the tongue. It needs minimal chewing.
- Food can be easily mashed with just a little pressure from a fork.
- Holds its shape on a spoon but falls easily if the spoon is tilted or lightly flicked.
These aren't appropriate
- Lumps should not be firm.
- It does not need biting.
- No mixed (thick - thin) textures for example cereal in milk, mince in gravy, and dried fruit in sponge.
Food examples
Meat / fish
- Must be finely minced or chopped to 4mm lump size for adults.
- Serve in a thick, smooth, non-pouring sauce or gravy.
- If it cannot be finely minced, it should be puréed.
Fruit
- Serve finely mashed or use a blender to finely chop it to 4mm lump size pieces.
- Drain any excess liquid that has separated.
Vegetables
- Must be cooked.
- Must be finely mashed or use a blender to finely chop it to 4mm lump size pieces.
- Drain any excess liquid that has separated.
Cereal
- Served thick with small soft 4mm lumps.
- Any milk/ fluid should not separate from the cereal.
- Drain any excess liquid before serving.
Rice
- Requires a sauce to moisten it and hold it together.
- Rice should not be sticky or gluey and should not separate into individual grains when cooked and served.
- May require a thick, smooth, non-pouring sauce to moisten and hold the rice together
Dessert
- The texture of very thick, smooth yoghurt or stewed apple in very thick custard. Any lumps must be up to 4mm in size.
- Or the texture of soft sponge cake with smooth filling, fully softened by mashing and mixing in with very thick, smooth custard.
- No ice-cream or jelly if a person requires thickened fluids (because these can change to thin fluid in the mouth).
No regular dry bread due to high choking risk.
